SKELETON STRUCTURE FOR FIREPROOF PARTITIONS."

SPECIFICATION forming para of Letters Patent No. 606,348, dated June es, 189s.

Application iiled July 28, 1897.

To cLZZ whom, it may concern.-

Be it known that l, PAUL KHNE, a citizen of the United States, residing in Stapleton, county of Richmond, State of New York, have invented certain new and useful Improve` ing material, which is arranged to be clamped between the lips or flanges of said clampingpieces by means of suitable keys or wedges, which pass through registering holes in the edges of the strut and through the recessed portions of the clamping-pieces.

The invention further consists of top and bottom T- irons, struts connected with the same at the top and bottom, and clamping pieces or strips applied and fastened to each edge of each strut, so as to hold between them the filling material.

ln the accompanying drawings, Figure lis 1 a broken side elevation showing the preferred form of my fireproof skeleton structure for partition-walls. Fig. 2 is a broken side elevation of another formof the invention. Fig. 3 is an enlarged transverse section, parts broken out, showing the construction at four meeting rooms, the intermediate portion of a partition, and at the part adjacent to a door- Fig. ais also an enlarged transverse section, parts removed, showing clearly the corner construction and a modified form `of clamping-piece. Fig. 5 is a detail perspective view showing the manner of connecting a strut with a T-iron; and Figs. 6 and 7 are respectively a detail transverse section and side elevation enlarged, showing the key or wedge connection of a clamping-piece with a strut. r

Referring to the drawings, 'A A represent, respectively, the top and. bottom Teirons of sel-iai no. 646,186. No maar) are clamping pieces or strips B, longitudi' nally recessed orwhich are U -shaped in cross section and which' are provided with side flanges b', these flanges being adapted to hold and bind the iillingbetween them inlthe manner now to be described. Y

Referring more particularly to Figsj and 7, it will be seen that each strut B is provided with a hole h2, which registers with corresponding holes b3, formed in tliefclampingstrips. Intothese holes areV driven from the opposite sides two keys or wedges DD', which `when driven forciblyV into the holes at opposite sides of the structure come in contact with and force the flanges of the opposite clamping strips toward each other, thus tightlybindingthe illingbetweenthem. The inclined faces of the wedges are so disposed as that when they are driven in they will act to force the clamping-strips inwardly against the filling.

In`Fig. 1 a form of filling is shown which consists of suitably-spaced laths or strips E, which are connected by means of interwoven wires e, the ends of which are passed through holes e in the flanges a of the T-ironsso that the` said wires can be connected therewith. I have in' the other figures shown rillingslabs E', but l do not limit myself to the use of either the described' or any other filling.

The clamping-strips shown at the extreme left of Fig. 3 are of modified form-that is to say, they are each formed of a laterally fold-V neck or web portions f and through the edges of the strut B.

To the framework of the door the filling F or its equivalent, as shown at the extreme right of Fig. 3, is connected and applied by means of the doubly-hanged sheet-metal strip G, which is applied to a metallic strut g, which is secured to the door-frame by means of suitable fastening-nails or the equivalent g', which are driven through the side flanges g2 of said doubly-flanged strip and through the side perforations of the strut g. At the left of Fig. 4 a clamping-strip ff f2 is shown,

which'is the equivalent of that shown at the left of Fig. 3 and is to be applied to one of the edges of a strut B in the main wall for supporting a partition-Wall extending at right angles thereto. This clamping-strip is api plied to one edge of the strut B, while to the other edge is applied a clamping-piece B',

similar to that shown in Figs.` 1 and 2, and' which extend at right angles relatively to eachV other, while between the said flanges the casing is formed with a triangular key head or rib h2. When the corner-post is set up, the

. ends of the filling material are inserted between the side flanges 7L h and the head h2, while the plastering T isapplied to the perforated sides of the strut H, so that the plastering or cement material can enter the perforations p, and thereby be prevented from 4o clipping off. The key-shaped head on the casing further strengthens and reinforces it in connection with the strut H, While at the same time and mainly it supports the filling I,material and partition against falling inwardly. The strut H is wired to the ceiling Y and floor T-irons in a similar manner to the partition-struts.

Having thus described my invention, what I claim is- 1. In a skeleton structure for fireproof partition-walls, the combination of a metallic 4strut provided with transverse holes near its edges, flanged clamping-strips applied to each edge and having transverse holes immediately adjacent to the fianges and' registering '.with lthe holes in the strut, andl keys or lwedges driven through the holes in the clamping-strips and strut and being in contact at each endwith the'fiat'surfa'ces of said flanges,

substantially as set'forth.

2. In a skeleton structure for firepro'of partition-walls, the combination with the ceiling land f'loor irons, and struts connected with ysaid irons and provided with transverse holes neary their edges, of U -shaped clamping-strips provided with holes rcgisterin g with the holes in said struts, and keys driven into the registering holes of the strips and struts,i"or clamping the filling material between the said velamping-strips, substantially as set forth.

Intestimony'that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

PAUL KUHNE.
